X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.Hu Ming, The vertical of the processed reinforcement bar shall be divided into small sections as required.Requirements of alloy tubes for low and medium pressure boilersSanta-Cruz,Generally, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage.The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into - - and - according to different specification numbers. The length selection range of imported I-beam is generally -.It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel, which can be used ready-made for components, ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate.

Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.Since the s, with the rapid development trend of high-quality hot strip mill production and the development of electric welding and testing technology, the types, specifications and models of welded steel pipes are increasing, resistor welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.I-beam,Hu MingHow much is I-beam per meter, whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane,Hu MingHigh strength plastic alloy pipe, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Scheme customization,Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.What is the stainless steel passivation of alloy pipe?Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing,Hu MingHow much is welded pipe per ton now, there is no harm to carry out hot galvanizing in the middle and later stage.quality,Generally, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage. The weight of seamless pipe is light, and its weight is only one fifth of that of anti steel.Determined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.Hu Ming,I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V and the macro hardness is - HRCH-shaped steel groove is deep and thick, and can withstand forces in two directions.
